if you have a locked cabinet in the office (assuming there is some sort of office?) can't each person come into the office for their medication, you sit down in front of them and give it to them?
failing that, if you have to go into each persons room, then you take their medication with you, sit down in front of them and give it to them.
am i right in that you have eight people to take care of?
i don't actually see what the problem is to be honest, provided that there is a locked unit somewhere on the premises to keep all the medication in and a suitable way of signing for it when you dispense it. there must already be something in place, so what exactly is your gripe - that you have to bend down? so you sit in a chair. that you have to cart a whole load of medication around with you? so do it one by one.
